How did dinosaurs die out? And if they did, why?CREATION: Most died during the Flood about 4400 years ago, and later, humans killed them for meat, to be a hero, or if it was terrorizing the village. Since they are cold- blooded, Most could not adapt to the post-flood enviornment. Some shrank due to the layer of water that the earth now lacked, since the flood was that layer in liquid form. In those days they were known as dragons.EVOLUTION: They roamed the earth about 65 million years ago, until an asteroid caused mass extinction in these large lizards. Dragon legends were based on pure imagination and a few ancient dinosaur fossils dug up by ancient peoples.
